A deep dive into the iOS backup/restore system

Domains.plist

Documentation of /System/Library/Backup/Domains.plist. File taken from iOS 16.4 iPhone SE 3. The file was removed in iOS 17.0

Values

Values in the plist. Other than SystemDomains, these are not really important and are just here for preservation sake.

A domain in domains.plist contains keys that determine what gets backed up for what types of devices and where (i.e. iCloud vs iTunes). Not all domains have each key. The only 2 keys that must be in every domain are RootPath and RelativePathsToBackupAndRestore. Some domains have the value ShouldDigest. I am not sure exactly what it means but I have included it for documentation purposes.

  • Version: "24.0"
  • SystemDomains: (Dictionary), see below
#!/bin/bash
#
# Enable TRIM support for 3rd Party SSDs. Works for Mountain Lion, should work on earlier OSes too.
# Tested on 10.8.2, 10.8.3, 10.8.5, 10.9.0, 10.9.1, 10.9.2, 10.9.3, and 10.9.4
#
# You may have to re-apply the fix after some system updates, including but not limited to those below:
# 10.9.X to 10.9.4
# 10.9.X to 10.9.3
# 10.9.X to 10.9.2
# 10.8.X to 10.8.3
